Description

This Standard specifies the material, dimensions, properties, tests, colour and marking requirements for polyethylene pipes and fusion fittings for use in gas mains and services. Provides for 5 classes of pipe having standard dimension ratios of 11, 17, 21, 26 and 32 suitable for maximum pressures of 100 to 420 kPa.

Scope

Part 1 of this Standard applies to polyethylene pipe for use in gas mains and services for direct burial and reliner applications. Such pipe is intended for use in the distribution of natural gas at pressures up to 4.2 bar (420 kPa).

It also applies to pipe for use with gas produced from liquefied petroleum gas (LPG) and mixtures of LPG and air where the partial pressure of the LPG component does not exceed 2 bar (200 kPa).

The pipe shall be formed from compound complying with AS 1685 which provides only for a high density polyethylene, coloured yellow.

This Standard does not apply to pipe for use with petroleum liquids, including liquid LPG and liquid pentane, or with manufactured or mixed gas distribution systems or systems which may contain more than 1 percent aromatics.
